I have lost my way here, but I did some tests to try to understand. If I 
use defcustom with a :set function this will be called when the elisp 
file is loaded. Why can't something similar be done for 
define-global-minor-mode also? It is a global mode and then :set is 
passed to defcustom, or?

BTW should not the name be define-globalized-minor-mode as was suggested 
before?
